Abstract Scope |
Modern computational tools across a range of applications use Integrated Computational Materials Engineering (ICME) techniques to provide a functionally robust framework for the creation of new structural metals where physical iteration can be reduced by predictive modeling. Finite element (FE) methods can be applied to realistic microstructures on different length scales to predict the influence of microstructural parameters on mechanical performance. In combination with thermodynamic and kinetic modeling tools, micromechanical FE modeling enable early and frequent vetting of composition and process variables on properties such as yield strength. Building a robust FE model depends on multiple variables, including use of simulated or experimentally observed 3D microstructure geometries, identification of valid single-phase material properties, utilization of functional homogenization schemes, and application of boundary conditions. FE modeling methodologies utilized within a novel high-strength austenitic steel project are discussed here along with their integration into a greater ICME alloy development framework. |
